Objective To observe the therapeutic efficacy of ozone injection in treating lumbar disc herniation. Methods One hundred and four patients with CT or MRI proved lumbar disc herniation, including 144 diseased lumbar discs, were enrolled in this study. The main complains were severe pain or numbness in the low back and lower limbs. Under the X-ray guidance, a 21 G needle was punctured into the disc, followed by an injection of 4-40 ml ozone (50 ug/ml) and 40 mg prednisolone acetate into intradiscal and paravertebral space. Results All patients were followed up for 3 to 84 months with an average time of 38 months. The last follow-up check was carried out in March of 2009. The total effective rate was 77.1%, with no occurrence of any serious complications. Conclusion The percutaneous injection of medical ozone into disc and paravertebral space is an effective and safe method for the treatment of lumbar disc herniation.

OBJECTIVETo investigate therapeutic effects of vacuum sealing drainage (VSD) in the treatment of soft tissue defect combined with tendon and bone exposure.

METHODSFrom October 2007 to February 2011, 397 patients (412 feet) with open ankle fracture and dislocation combined with soft tissue defected were treated by VSD. There were 301 males and 96 females with an average age of 36 years (ranging age from 20 to 73 years). According to AO classification, 74 feet were type I, 211 feet were type II, 108 feet were type III and 19 feet were type IV. The mean time from injury to operation was 5.6 h ( 2 to 12 h). The mean treatment time of was 10 months (4 to 19 months).

RESULTSOne hundred and forty-one patients were primarily healed, 97 patients were sutured at stage II. Split-thick skin grafting was performed at stage II was performed in 103 patients; free flap transplantation was performed in 25 patients. Three of the 34 patients with infection were removed steel plate; Eviscerate flap coverage wound was performed in 14 patients caused by the first metatarsal bone exposure; Toe amputation were performed in 22 cases caused by toes necrosis. Tarsometatarasl joints perforators' surgery was performed in 10 patients with forefeet necrosis. Thirty hundred and six patients were followed up from 3 to 20 months (averaged 10 months). The wounds healed well.

CONCLUSIONVSD for soft tissue defects caused by ankle injury is a simple and effective method, but can not replace debridement and transfer flap.

The specification of decoction pieces and quality uniformity are the important factors to influence the efficacy of clinical medicine. Considering the deficiency of diversity, poor quality uniformity and confusion of decoction pieces specifications, we first propose a new idea of precision decoction pieces (PDP) based on clinical demands and fresh-processed technology. In order to explain the idea, a study case of aconite SUP is provided, including the optimized specification design, processing technology, extraction effects, quality uniformity, and toxic and efficacy variation and so on. The results showed that preparing 5 mm PDP by fresh-cutting is rather simple and practicable, with high efficiency and large yield; then, this technology could significantly decrease the ingredients loss and increase the efficacy components; moreover, it was helpful for achieving the quality uniformity and best extraction effects. This work revealed the quality superiority of PDP, and provided a good strategy and example for the standard of decoction pieces specification and modernization of processing technology.

Objective: To examine the expression of glucocorticoid receptor in human colon cancinoma tis-sues and call lines and to explore the survival of colon cancer cell lines treated with dexamethasone alone or in combination with 5-Fu and L-OHP in a way of dexamethasone pretreatment or co-administration in vitro.Methods: The expression of glucocorticoid receptor was detected in 61 cases of colon cancer tissue samples and 4 types of colon cancer cell lines by immunohistochemistry. Apoptosis was detected by Hoechst33342 staining and flow cytometry. MTT assay was employed to detect the chemosensitivity of colon carcinoma cells to L-OHP and 5-Fu with dexamethasone pretreatment for 24 hours or co-administretion. Results: Positive GR expression was found in 57.3% colon cancer tissue samples and in Lovo and HCT-116 cell lines, not in HT-29 and SW-480. Apoptosis was detected in GR-expressed Lovo and HCT-116 cells at 72 hours after 1×10~(-4)mol/L Dex treatment, and the rates of apoptosis were higher than those in the control groups without Dex (P<0.01),GR-negative cells, HT-29 and SW-480 even treated with 1 × 10~(-4)mol/L Dex for 72 hours. Pretreatment and co-administration for Lovo cells with 1×10~(-4)mol/L Dex could decrease the IC50 of L-OHP from 13.7±1:1.3μg/mL to 5.9±0.6μg/mL and 4.8±0.7μg/mL, respectively. IC50 of 5-Fu was decreased from 72.2±8.1 μg/mL to 21.1±4.1μg/mL and 18.6±4.0μg/mL, respectively. Conclusion: There is expression of glucocorticoid receptor in part of colon carcinoma tissue samples and cell lines. Apoptosis does occur in GR-expressed Lovo and HCT-116 cells induced by dexamethasone in vitro. Pretreatment for 24h and co-administration with Dex can increase the chemosensitivity of Lovo cells to L-OHP and 5-Fu.
